*Results of the BMI Calculator are based on averages. Keep in mind that the BMI calculator may overestimate body fat in those with a muscular build. A BMI Calculator is designed to assess your relative fitness but it is NOT a calculation of body fat percentage.

If your BMI is below 18.5: Your BMI is considered underweight. Keep in mind that an underweight BMI calculation may pose certain health risks. Please consult your healthcare provider for more information about BMI calculations.

If your BMI is between 18.5-24.9: Congratulations! Your BMI is considered normal. This healthy weight helps reduce your risk of serious health conditions and means you’re close to your fitness goals.

If your BMI is above 30: Your BMI is considered overweight. Being overweight may increase your risk of cardiovascular disease. Consider making lifestyle changes through healthy eating and fitness to improve your health. Our Couch to 5K training plan is a great place to start.
